Unfortunately, it's not that simple. Older style Xen (like what is in RHEL-5) use the "/sys/devices/xen-backend" path; I'm assuming new-style Xen (like you are possibly using) use the new style path. What dom0 kernel version are you using? If you submit a patch to try out both paths, that will probably be acceptable. -- Chris Lalancette -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
